I would like to append pdf files, i ll be getting NSData from server which i am saving as PDF, i want to add more data to existing PDF, i tried appending NSData which is appending the no.of bytes but if i save it as PDF then it only saves the appended part not the main part.
Example:
NSMutableData of existing PDF is firstdata NSData of second PDF that i got from server is seconddata
now i have appended firstdata with seconddata and save it in a file this will only save the PDF part that is there in seconddata.
can anyone help me in solving this.
